Domain Health is built for IT admins, MSPs and consultants who need clear answers and client-ready documentation. Enter a domain and tap Check Domain Health. The app runs 26 checks across the parent zone, nameservers, SOA record, MX and email authentication, and the www host, and gives every check a clear status. Client-ready PDF reports: - Full Report: cover page, table of contents, summary and every check with its status, impact and how to fix it - Executive Summary: a one-page overview with overall status, key findings, priority areas and recommendations - White label: your company name, logo, accent and background colors, header line thickness and report title - Save, print or send the PDF from the share sheet Email checks: - SPF: finds missing or duplicate records, explains every mechanism and flags a permissive or missing "all" - DMARC: validates the policy and subdomain policy, reporting addresses, alignment and percentage - MX: consistency across your nameservers, hostname validity, public IPs, CNAME use, record count and null MX (RFC 7505) - PTR (reverse DNS) records of your mail servers DNS checks: - Parent domain: delegation at the TLD compared with your own nameservers, listed nameservers and glue records - Nameservers: open recursion, glue consistency, authoritative answers, number of nameservers, subnet diversity and TCP connectivity - SOA: serial number format and consistency across nameservers, MNAME, refresh, retry, expire and minimum TTL Web checks: - Public IP and CNAME of the www host - SSL certificate validity and days until expiry, with a warning when it expires within 30 days - HSTS status Accurate by design: - Checks that depend on one specific server query the parent zone and each of your nameservers directly - All other lookups use DNS over HTTPS through Google, Cloudflare, DNS.SB or NextDNS, selectable in Settings - Every check shows what was queried, the result, its impact, how to fix it and best practices, with links to further reading History and privacy: - Every check is saved in History, grouped by domain.
